FILLING-MACHINE FOR CANS,&C. m

SPECEFICATION forming part of Letters Patent No. 310,268, dated January6, 1885.

, A pplicfiton tiled October 9, IRQ-l.

Be it known that l, .Hires .'l. Goiaii'AN, et' 'Feinescah State ofCalifornia, have invented an Improvement in lililling-Machines for Cansand other Vessels; and I hereby declare the following to be Va full,clear, and exact description thereof.

My invention relates to a new and useful filliiig-niachiiies for cansand other vessels of that class in which the supply for filling theseries of vessels is regulated automatically by means of a displacementweight or body; and my invention consists in the arrangement of tanks,measuring-cups, displacemeiitbody, and feed and dischargeinecliaiiisms,licrei uafter described, together with details of construetion.

rlhe object of my invention is to provide a machine which is adapted toprovide autoiiiatically a supply of liquid, and to feed the supply instated quantiticsto the cans or other vessels to be filled.

Referring to the accompanying drawing for a more complete explanationot' myinif'ention, the figure is a perspective view of my invention, aportion of the tank C being broken away to show the incasuring-cups, anda portion of the displacementlbody being broken to show its hollowbottomless character.

A is a frame, in the top of which is mounted the inain tank. E, belowwhich is the secondary or feed tank C. 4Between these tanks is theconnecting spout or pipe b, opening from the bottom of the main tank anddischarginginto the tank C near the bottom. In this pipe is a cock, b',for hand use, while on its top is a valve, c, connected with which is acord, D, passing upward over suitable pulleys, d, and down toa float, E,within the feed-tank.

F is a tray, upon which are set the series of cans Gto be iilled withthe liquid.

Vithin the tank C are an equal number of measuring-cups, II, havingoutlet-pipes li extending downwardly through tlie bottom of the tank andadapted to discharge into the cans G- below. The pipes h project abovethe bottoniof tank C a convenient distance to allow of the cups H beingscrewed or otherwise detachably fastened to them. Each cup, togetherwith that portion of the pipe 7il above the cock, has a capacity equalto that of the can immediately below. rllhc measuring-cups (No model.)

are easily detached t'roiii the pipes 7i, and when this is done othercups of a different size may be substituted, whereby the quantity ot'liquid ber ofloiigitudinal bars which play past the pipes 7i, and areconnected with the handles i' of stop-cocks .l in said pipes. ',lhcmovement of the lever-frame .I' iii one direction opens the st7op-cocksJ, while its movement iii the reverse direction closes them.

Tithiii the tank C is a displaccincnt-body,V \V, to the top of which isconnected a cord, in, passing up over and around suitablepulleys, lr,and down to a ti'eadlc, 1li, willi/iin reach ot' the operator.

The operation of the device is as follows: A large quantity ofthe liquidis contained iii the inaiu tank l, from which a portion is allowed topass down into the feed-tank C (the cocks J' being closed) until itreaches a level above the tops of the cups, while the displacement-bodyrests on the bottom of the tank. rlhe body \V is now withdrawn, therebycausing tlielevel ofthe liquid to fall considerably below the tops ofthecups, leaving them full. Vhile the body is so withdrawn the cocks J aresimultaneously opened by the lcver-franie, allowing the contents of thecups and pipes to drop into the cans beneath. Then the level of theliquid falls in the tank C, the float E falls with it, opening the valvec in the main tank and allowing the liquid to pass down through the pipeb into tank C until its level has reached a point immediately below thetops of the cups, at which point (governed by the length of the cord D)the valve c closes, owing to the buoyancy of the iioat. Meanwhile theliquid in the cups has fallen into the cans on the tray. The cocks J arenow closed and the body W allowed to descend, thereby refilling thecups. Its withdrawal leaves them again full for another operation. Toaccom` plish this result the tient-connection between the feed-tank Cand the main tank B will be accurately adjusted in such a manner thatits operati on upon the valve c will allow a quantity ofvliquid to passinto the tank C equal to that drawn oil by the overflow into cups Il,and will shut it oftl when the liquid has reached the properlevel. Thesize of the displacement- IOO , outlet controlled bythe stop-cock bodyXV will be such that its operation may have the effect of fillingmeasuring-cups II by its insertion into the tank, and to lower the levelof the liquid in said tank to the required distance by its removal.

For the purpose of obtaininga displacement without having too muchbuoyancy or more weight than is necessary to raise the treadle to itsproper position, I construct the displacement-body Vin the followingmanner: It consists of a hollow casing or chamber of anysuitable shapeand having no bottom. This casing is forced down into the liquid, afterthe manner of a diving-bell, and the body of 'air contained within it islet oi't by means ofan After the air is thus let oii the stop-cock isclosed, whereby the chamber YV, while having little buoyancy, has stillthe required displacement.

The whole device is simple in its construction, and may be opera* edrapidly and with accuracy.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. In a machine l'or iilling cans or other vessels, a main Simply-tank,a secondary or feed tank having independent measuring receptacles orcups within it, adapted to supply the cans or vessels to be iilled, adisplacementbody and means for raising it from and lowering it intotheliquid in theIeed-tank,whereby its level is raised to ilow over intothe measuring-receptacles, and lowered to cut off their supply, aconnection between the main tank and feed-tank, and a mechanism operatedby the rising or falling level olliquid in the feedtank to shut ott thesaid connection, or open it to renew the supply, substantially as here-yin described.

2. In a machine for lilling cans or other vessels, a main supply-tank, asecondary or Vl'eed tank having the independent measuring receptaclesyor cups II within it, adapted to supply the cans or vessels to beiilled, a displacement-body and means for raising it from and loweringit into the liquid in the feedtank, whereby its level is raised to flowover into the measuring-cups, and lowered to cut ofi' their supply, thepipe Z), connecting the main tank with the feed-tank, and the meehanismby which the supply from the main tank is cut ot' or opened,/consistingol" the lleat E in the iced-tank, the cord D, and the valve c, governingpipe l), substantially as herein described. v

3. In a idling-machine l'or cans or other vessels, the series ot'measuring-cups II within the ieedtank, adapted to receive their statedsupply by the rise of the liquid in said tank, and tov discharge itthrough independent pipes into the series of cans er other vesselsbelow, substantially as herein dcscribed.

4. In a machine `for iilling cans or other vessels, the series ofn'ieasuring-cups II within the feed-tank, adapted to receive theirstated supply by the rise of the liquid in said tank. and to dischargeit into the vessels to be filled, said cups being detachable for thesubstitution of others of different capacity, substantially as and forthe purpose herein described.

7. Ina iilling-machine for cans and other vessels, the series ot"discharge-pipes h, having cocks J', with handles i, in combination withthe swinging lever frame I, secured to said handles, by which -the cocksare operated, substantially as herein described.

S. In a machine for filling cans and other vessels, the feed-tank C,having the measuring-cups II, with outlet-pipes li, having cocks J, withhandles 1'., the displacement-body lW, by which the measuring-cups areiilled, and the reciprocating lever frame I, secured to handles fi,whereby the cocks J are operated, substantially as herein described.
